Moscoso had a nice 3.38 ERA in 21 starts and two relief appearances for the A’s in 2011 before being sent to the Rockies in last winter’s Seth Smith deal. Like most everyone else on Colorado’s pitching staff, he was a bust last season, finishing with a 6.12 ERA in three starts and 20 relief appearances. Back in a pitcher friendly ballpark in Kansas City, he has a chance to reemerge as a useful swingman. He’ll make just over the minimum, so he’s a nice grab. Grade: B

Hayes, 28, is a very generic backup-type. He gets pretty good marks for his defense, but he’s hit .217/.266/.361 in 332 major league at-bats. The Royals shouldn’t be content to let him play behind Salvador Perez next season. Grade D

Wood had a 3.75 ERA and 62 strikeouts in 69 2/3 innings for the Royals in 2011 before Tommy John surgery, but Kansas City didn’t think it was worth paying him $1 million or so to stick around for another year. It’s the Indians’ gain. Wood throws in the mid-90s and has a decent enough slider. I doubt he’ll take another step forward, but the price was certainly right. Grade B+

At 28, Casilla might yet have a future as a utilityman. Still, he’s had plenty of chances already and it’s gotten him a lifetime .250/.305/.334 line in 1,580 at-bats. The Orioles would have to pay $1.5 million-$2 million to keep him through the arbitration process, and there’s a real chance they could have gotten him on a minor league contract had they been more patient. Grade D

Roenicke is another case of a team throwing away a useful reliever simply because he’s eligible for arbitration. Roenicke, though, doesn’t stand to make much more than $1 million, and that’s a bargain for a guy who had a 3.25 ERA in 88 2/3 innings out of the pen for the Rockies last season. Yes, 88 2/3 innings. His peripherals weren’t good, and I do wonder if the heavy workload will take its toll next year. But for $1 million, there’s hardly any risk. Grade A

Field, on the other hand, isn’t very likely to be useful. He strikes out plenty, and his still-modest minor league power numbers were amplified by the hitter’s parks in the Rockies system. The way I see it, he doesn’t have the glove to make it as a full-time shortstop or the bat to be useful as a utilityman. But at least he’ll fit right in on the Twins. Grade D

Cubs claim RHP Zach Putnam from the Rockies

Exclusively a reliever since mid-2010, Putnam has been only a modest success in the minors with his 89-92 mph fastball-splitter combination, never finishing with a sub-3.00 ERA at any level. It seems doubtful that he stands much chance of surviving in a major league bullpen. Grade D

Brewers claim RHP Arecnio Leon from the Astros

Leon turned 26 in September, and he spent last season amassing a 4.52 ERA as a Double-A reliever. He has a big fastball, but he’s never been a real prospect. Grade D

Adam Wainwright tossed a spring-high 93 pitches in a Grapefruit League outing Tuesday afternoon against the Marlins and was declared the Cardinals’ Opening Night starter after the outing by manager Mike Matheny.
